Plain English Summary

Background and study aims
Cellulite is a skin condition that can lead to skin imperfections, caused by uneven distribution of fat, It is seen most commonly in the thighs, hips and abdomen of both women and men. Exercise and a healthy diet can reduce the appearance of cellulite, but cannot completely eliminate it. Weight loss is key to reducing cellulite, whether this is achieved by diet or through exercising to burn calories and increase metabolism.
Herbal supplements can help to achieve weight loss faster than diet or exercise alone, as they increase the rate of burning fats. Some supplements containing compounds from plants can also help to reduce cellulite through removing toxins, draining fluids, reducing inflammation and firming and toning the skin, along with burning fat.
The aim of this study is to determine the efficacy of SelectSIEVE® Rainbow, a food supplement that contains a mixture of herbal and plant extracts including black rice, kiwi, orange and pineapple extract, on reducing the appearance of cellulite and on weight control.

Who can participate?
Healthy women aged 18-55 with cellulite and a BMI ranging from 23-30

What does the study involve?
Participants will be asked to take one capsule per day, containing either the food supplement (SelectSIEVE® Rainbow) or a placebo, for 56 days. Participants will be evaluated for changes in the appearance of their cellulite, skin elasticity and firmness, thickness of fatty layers and body measurements such as weight and circumferences. These measurements will be taken before starting the treatment, after 28 days and after 56 days. Participants will also be asked to take part in an interview for a self-assessment evaluation.

What are the possible benefits and risks of participating?
The possible benefit to participants is a reduction in the appearance of cellulite-related skin imperfections and a slimming effect. There are no known risks to participants, aside from a minimal risk of allergy or intolerance to the food supplement.

Cellulite-derived skin imperfections and localised adiposity at level of thighs/hip/waistline


60 healthy female participants were randomly allocated evenly into either the treatment or placebo group using a computer generated restricted randomisation list. Participants in the treatment group took capsules containing the active product (SelectSIEVE® Rainbow), a food supplement containing a mixture of herbal extracts, maltodextrins and natural dye. Participants in the placebo group took placebo capsules, where the active product was substituted by maltodextrins. Both groups took 1 capsule per day with a drink of water, either before lunch or their main meal, for 56 days. Participants in both groups were asked to follow a personalised alimentary diet, calculated in order to reduce their daily calorie intake by 300 kcal. Participants were also asked to use a body cream in place of their standard cream for body care.

Primary outcome measure

The following outcomes were measured at day 0 (beginning of the treatment), day 28 and day 56 of treatment:
1. Cellulite-induced alteration of the skin microcirculation, measured by thermographic imaging
2. Clinical-dermatological evaluation of the cellulite-derived skin imperfections ("Orange peel" skin appearance ) carried out by a dermatologist in accordance to clinical scores
3. Thickness of the subcutaneous fatty layer measured by an ultrasound technique (using BX2000 BodyMetrix)

Secondary outcome measures

The following outcomes were measured at day 0 (beginning of the treatment), day 28 and day 56 of treatment:
1. Body weight by electric balance and height by stadiometer (for BMI determination)
2. Body circumferences (tights, hips, waistline) by a flexible meter
3. Evaluation of safety (adverse effects and tolerability) by monitoring adverse effects
